摘要
STEP（theSTandardfortheExchangeofProductmodeldata）标准是一个服务于CAD。CAM领域的覆盖产品整个生命周期的形式化的产品数据交换标准，其应用协议的研究开发与实现具有广泛的应用价值．本文主要介绍了STEP标准应用协议配置控制设计STEPpart203的前后处理器的设计与实现，包括应用协议的EXPRESS描述编译、几何拓扑映射、面片合成、中性文件交换、在SUNSPARCworkstation上的处理器实现和零件输入输出测试等内容．
STEP(the STandard for the Exchange of Product model data) is an important, formal,and product-life--cycle--covering product data exchange standard in CAD/CAM. This paper mainlyintroduces the design and implementation of the processors of application protocol STEP part 203,including the compilation of protocol description in EXPRESS, geometrical and topological modelmapping, facets combination and the neutral file exchange, etc.. The processors were implementedon SUN SPARC workstation and have gone through the test on various parts.
